The girl is a crossdressing Shino. Shino is the princess in the story who died 5 years ago. Shino contains the spirit of the Princess as well as one of the descendants. Sousuke contains the spirit of Yoshiro the dog (who probably also died back then) and that makes him the "husband" of the story. The one who haunted the forest was a "lure" of the demon to capture men. I don't think that Hamaji is the "Princess" of this story as no one was particularly worried about her until the end of the episode and Sousuke is more worried about Shino.

Spoiler:

Hmm, so then Shino is biologically a girl who pretends to be a guy? But why pretend when even that kid Kenta knows she's a she.

Pretty interesting first episode, like the animation and character style so far...though the first ep felt like it moved quite quickly.
